It is our belief that soft wash chemicals, in their diluted form and as used on a customer's property, should be legal and  safe for people, materials and our environment.

Benz Blackwash at 5:1-10:1 dilution is not classed by the EU, PCD or HSE as corrosive or hazardous to people or our environment.

We designed this powerful biocide product specifically for tough stain removal from rendered walls, footpaths, concrete patios & drives, roofs, sandstone, limestone and most other exterior surfaces.

The active ingredient is sodium hypochlorite, a powerful oxidiser that removes the most troublesome of black, red and green stains from exterior hard surfaces.

The high quality surfactant used in Blackwash complies with all EU biodegradability requirements

This powerful surfactant "sticks" the active ingredient to the surface – ensuring a higher contact time – which means the low, and therefore safe, concentrations of chlorine in Blackwash can work with extremely high effectiveness.

This means Blackwash is safer for the operator, for the general public, and for our environment than formulations that contain high concentrations of chlorine.

♦◊♦

Blackwash is the only sodium hypochlorite based soft wash biocide that has full government approval *

It is approved by:

• The Irish PCD (Pesticide Control Division)
• The UK HSE (Health & Safety Executive)


We supply Blackwash as a specialised ready-mixed soft wash biocide that does not bio-accumulate.

It produces exceptionally rapid results on porous surfaces – such as render – and produces a near instant cleaning effect on smooth, non-porous surfaces such as cladding and UPVC.



It can be used as a stand-alone soft wash solution or in conjunction with power washing or Benz Biocidal Wash.

    Why is a high quality surfactant so important?

    All surfactants are not created equal. The properties can vary dramatically and it is not a matter of "just adding Fairy Liquid to hypochlorite".

    BENZ Blackwash uses a special type of highest quality surfactant to:

    1) Maintain a stable solution that can be stored for longer than would be the case with cheap, less effective surfactants.

    2) Formulate a solution that is a highly effective "wetting agent" that rapidly soaks into the "biofilm" (the layer of biological growth that gives rise to the dirty stains that customers want removed) and thus increases the effectiveness and speed of operation of the active ingredient.

    3) Ensure that the the surfactant does not break down the sodium hypchlorite – which many inferior surfactants will do – and thus minimise the production of chlorine ( a big problem if strong sodium hypochlorite is used with a cheap and inferior surfactant).

    4) Create a product that adheres (or "sticks") effectively to the surface being cleaned, ensuring the active ingredient stays in contact with the biological growths for the longest possible time (which enables Blackwash to be highly effective using a safer % of chlorine than would otherwise be the case).

    5) Reduce run-off from walls and roofs into drains and the environment.

    6) Ensure the surfactant complies with all EU biodegradability requirements for surfactants.

    Because of the high quality surfactant, 5 litres of Blackwash will do much more work, more effectively, covering a larger area, than will 5 litres of ordinary commercial sodium hypochlorite – and it will do it far more safely.

    What makes Blackwash safer than industrial sodium hypochlorite?

    Unlike commercial sodium hypochlorite that has a 15% concentration of chlorine, and which therefore has intrinsic dangers to the operator and customer, BENZ Blackwash as delivered in concentrated form contains 10% chlorine.

    This lower % of chlorine means the product is both safer and will last longer that raw industrial sodium hypochlorite. This is because the higher the % chlorine content, the faster the product will degrade.

    And as applied to actual surfaces Benz Blackwash contains only 0.5-2% chlorine – making it safe for the operator, customer, the customer's property, and the general public.

    High strength sodium hypochlorite poses an high health risk. Most Health & Safety reps in large companies will not allow their employees spray corrosive liquids, which is why we created BENZ Blackwash to be safe for all concerned.

    We use special vented caps. Blackwash containers come with special vented caps which allow for the gradual and completely safe release of a small amount of vapour that the product naturally produces. If Blackwash is decanted into another container always ensure vented caps are used.


    Quality control: To ensure the highest possible production quality we have Blackwash manufactured for us by one of Ireland's leading chemical companies who hold the ISO 9001:2000 accreditation in quality control.

      Is Blackwash safe to use on UPVC?

      Yes. We recommend using Blackwash at 10:1 on UPVC as at higher concentrations the UPVC may turn salmon pink if not rinsed off after 10 minutes. This is nothing to be concerned about, and the surface will return to its natural white in a few hours, but customers are happier if this does not happen.

      Blackwash is a highly effective way to clean ingrained black staining from UPVC guttering, fascia, soffits, windows, doors, and frames. It brings them up wonderfully clean, ready for rinsing with a standard Water Fed Pole (WFP) window cleaning system. 

      How to apply Blackwash to UPVC: Simply spray using a Benz 10 Soft Wash Spray Nozzle and rinse off after about 15-30 minutes. We use a power washer with a rinsing nozzle that shoots a low pressure jet (you can put your hand in front of it) that mostly eliminates the need for brushing or scrubbing. The water force is usually enough to shift the dirt without damaging the surface.

      If you don't have power washer you can use a water fed pole with a brush to rinse off Blackwash. We've found this especially effective for smaller jobs, when it's not worth the time needed to set up a power washer.

      Btw: Benz Blackwash is excellent for giving windows a special gleam and sparkle that customers love.

      Is Blackwash safe to use on render?

      Yes, completely safe. Watch this video for a quick explanation.

       

       

      Does Blackwash damage render by leaving hydrochloric acid in the substrate?

      No. Not at all.

      KRend – one of the largest suppliers of wall render – in their own words (from a pdf they supply on recommended methods of cleaning efflorescence from their render) state:

      "Generally, an 8% solution of commercial grade hydrochloric acid is used. The acid concentration can be adjusted to suit individual circumstances; a less concentrated solution will require more applications to remove lime bloom but will be less likely to result in an acid etched appearance."

      We think it reasonable to any clear-thinking person that if KRend advocate the use of hydrochloric acid to clean their products, the extremely small amount that may be produced by the application of Benz Blackwash is certainly acceptable.

      However, we wanted to be 100% sure that Blackwash is safe to clean KRend, and by extrapolation, all other renders, so we asked the chemist in charge of developing Blackwash what the reality was. This is his response:

      "Given the dilution you are using (5:1–10:1) it would not be possible to produce 8% hydrochloric acid. The amount, if any, produced would be minimal as hypochlorite is alkaline. Also I assume your usage instructions include a thorough rinsing after use (they do) which will wash away all by-products or residues from the cleaning process."

      We think these combined statements should be enough for any clear-minded and reasonable person to feel safe and confident in using Blackwash to clean KRend and other renders.

      What are the problems with using higher concentrations of chlorine at 3%, 4%, 5%, 6% or even stronger?

      Because concentrations of over 2% available chlorine (Benz Blackwash diluted 5:1) are corrosive to building materials, windows, rubber seals, gutter seals, and so on. It can also damage equipment such as pumps and poses a severe health and safety risk to people and our environment (scroll down for detailed Health and Safety and environmental information).

      Therefore we created Benz Blackwash to be as safe as possible for people and property. You'll find that your customers will appreciate the fact that you are using a product that is government approved for the professional cleaning of exterior hard surfaces.

      Sometimes applying two, or occasionally three, treatments – rinsing between applications – is a small price to pay for maintaining the safety of a customer's property, ensuring the customer stays safe, and ensuring the operator stays safe. And of course it's a small price to pay for protecting our environment, which we all depend upon for our survival and well-being.

        Why not use industrial 15% chlorine sodium hypochlorite?

        Industrial sodium hypochlorite is vastly less effective per unit quantity – and much less kind to our environment, humans, and our customer's property – than is Benz Blackwash.

        At first glance we know it may appear that similar results to Benz Blackwash could be achieved using cheap industrial grade sodium hypochlorite. But ordinary 15% chlorine sodium hypochlorate has a number of serious drawbacks and real dangers.

        Note: All sodium hypochlorite is not created equal. The quality (strength and purity) of the cheaper products can vary. As is usually the case, we get the quality we pay for.

        Btw: Did you know that the higher the strength of sodium hypochlorite the faster it degrades when stored? So because Benz Blackwash is formulated using a relatively low concentration of sodium hypochlorite, it can be stored for longer than 15% chlorine sodium hypochlorite.


        Dangers arise from the high level of "run off" from the surface being cleaned when using industrial sodium hypochlorite:

        • The contact time with the biological growths is low, therefore needing much more sodium hypochlorite to be applied than is the case with Blackwash.
        • Because a higher concentration of sodium hypochlorite is necessary – with much higher levels of available chlorine – the increased risk of harm to people, property, and our environment is significant.


        The dangers of using high chlorine industrial sodium hypochlorite:

        • Because of the high concentration of sodium hypochlorite needed to achieve the same results as Blackwash, the danger of damaging the surfaces of a customer's property increases.
        • Because of the high level of available chlorine the danger to the operator and to anyone in the working area is much greater than when using Benz Blackwash.
        • The legalities of transporting 15% chlorine sodium hypochlorite in contractor's vans is decidely uncertain. 20/25 litre containers can only be legally shipped by a specialised Hazchem courier. So if you are carrying 15% sodium hypochlorite around in 20/25 L containers it would be wise to check on the current laws regarding its use and transportation.

          Imagine the horrendous burns that a driver, passengers, and general public could sustain if a container of strong chlorine sodium hypochlorite would cause if it were to split open in the event of an accident. And of course the spillage of toxic chemicals into the environment is also an important concern for us all today, and a serious contravention of EU legislation.

          Btw: If the possible human and environmental cost of using high chlorine sodium hypochlorite is not enough to dissuade you, now think of the possible legal, and subsequent financial, repercussions ...

          In contrast, because Benz Blackwash contains a lower concentration of sodium hypochlorite it is much safer to transport, especially in 5L containers (which do not require Hazchem shipping).

        It is highly unlikely that commercial sodium hypochlorite will have an SDS sheet

        • An SDS (Safety Data Sheet) is an essential Health and Safety document that all companies should require a contractor to produce prior to starting work on their property.
        • Blackwash comes with two SDS sheets and is also backed up by clear instruction guides and how-to videos for its safe and competent professional use. And of course it comes complete with our – free – ongoing support via phone and email.
        • The sodium hypochlorite we use in Blackwash is supplied by a REACH registered manufacturer, which may not be the case for the cheaper sodium hypochlorite products on the market.


            You will have no support when using high chlorine sodium hypochlorite

            • Using commercial sodium hypochlorite you are very much on your own, without any kind of support.
            • You will be responsible for sourcing the sodium hypochlorite, a long-lasting fragrance, and a surfactant that maintains a stable solution and has the required wetting and surface adhesion characteristics that are necessary to create an effective cleaning solution. But by using Benz Blackwash you only make one simple purchase, saving a lot of time that could be more profitably spent cleaning your customer's properties.
            • You will have to figure out how best to mix it with a surfactant and fragrance, decide on the best equipment to apply it to surfaces, and how to use it in ways that allow for its inherent dangers in a variety of situations and on a variety of properties and surfaces. Did you know that many cheap, poor quality surfactants will break down the sodium hypochlorite before the contractor even gets to use it?
            • In contrast Benz Blackwash comes in convenient, easy-to-use ready-mixed containers. This eliminates the dangers and time-consuming hassles associated with using commercial sodium hypochlorite.
            • And when you purchase Blackwash it comes with unlimited professional support by phone and email – as well as our Trade Tips newsletter and Facebook Page. You will enjoy the benefit of our combined hands-on experience and knowledge of running two soft wash businesses – completely free.

             

            Btw – Your Insurance Cover: Because of the high risk to the operator, customers, customer's property, and our environment (the legal consequences of infringing government legislation are increasingly serious) from using high strength industrial sodium hypochlorite, we suggest talking to your insurance company about the possible consequences before using it.

            How much does Blackwash really cost?

            The hidden costs of using industrial sodium hypochlorite:

            • Using unapproved sodium hypochlorite, and unapproved additives such as surfactant and fragrance, is ILLEGAL and leaves the user open to prosecution, invalid insurance and fines.
            • Shipping costs – Hazchem shipping is extremely expensive, even for delivery of only 20 Litres.
            • The financial and time cost of adding fragrance.
            • The financial and time cost of adding surfactant (btw: there are literally thousands of surfactants – do you really know which one to choose to get the qualities you need to create a truly professional soft washing product that will be chemically stable?).
            • The time wasted in mixing up the ingredients could be more profitably spent earning far more money by soft washing a customer's property.


            Benz Blackwash prices on the other hand include ready-mixed fragrance and the highest quality surfactant – and include FREE SHIPPING.

            We believe that, in real terms, the small extra investment in BENZ Blackwash is more than justified given the:

            • Enhanced performance compared to industrial sodium hypochlorite and poor quality surfactants.
            • Greater safety for the operator, surfaces, the general public, and our environment.
            • Lack of unpleasant "swimming pool" or "bleach" odours.
            • Supply of professional Safety Data Sheets required by all large companies employing cleaning contractors.
            • Peace of mind that comes from knowing you are using a safe product.

            Which companies recommend Blackwash for cleaning their products?

            Sodium hypochlorite – at the level of concentration as used in Benz Blackwash – is recommended by the leading render manufacturers KRend and Weber as being suitable for cleaning the surfaces of buildings coated with their products. Also by Kingspan, the leading manufacturer of industrial steel cladding.

            Ordinary industrial sodium hypochlorite with high levels of chlorine will leave behind excessive salts that could potentially damage the surface being cleaned, causing deterioration.

            But Benz Blackwash has been formulated so the minimum amount of chlorine is needed for stain removal – less than 2% on the heaviest of soiling – thus salts are kept to minimum.

            The breakdown of chlorine into common salt is the reason we thoroughly rinse surfaces after stain removal with plenty of fresh water.
             

            Watch this short (only 1:38) video see the stunningly fast and dramatic way Benz Blackwash cleans this timber cladding: (This effect was achieved using Blackwash at 10:1 dilution, which means only 1% chlorine is being applied, with no unpleasant odour)

            Note: After getting the timber clean we recommend using Benz Biocical Wash for ongoing maintenance involving repeated treatments. The active ingredient in Biocidal Wash is a powerful wood preserver that helps prevent wet and dry rot, as well as offering long-term protection from re-infestation by algae spores.

             

            Softwashing Tarmac

            In general we do not advise using Blackwash to clean tarmac. Wet down any tarmac that may be exposed to run-off from the surfaces being cleaned before applying Benz Blackwash.

            We suggest treating tarmac with Benz Biocidal Wash at 50:1 (25:1 or two coats at 50:1 for heavy infestation), which will usually show excellent results within 24 hours.

              Sodium Hypochlorite: The facts

              Common everyday uses of sodium hypochlorite: Babies bottle sterilising fluids contain 2% sodium hypochlorite. We bathe our children in swimming pools for hours at a time at up to 0.25% sodium hypocholrite and drink chlorinated water with up to 0.005% sodium hypoclorite. And dentists use it during deep surgery.

              Benz Blackwash contains sodium hypochlorite as an oxidiser. It is this oxidising process that makes Blackwash such a highly effective cleaning solution. Sodium hypochlorite's strength in a product and during application are normally referred to by a percentage of chlorine.


                There has been much confusion about the reality of the effect of sodium hypochlorite, when used responsibly and in accordance with Health and Safety guidelines, on both humans and the environment.

                This is because most easily available data refers to sodium hypochlorite above 10% strength.

                And its properties differ dramatically when used in a 25% concentration for industrial bleach to 0.005% concentration in our drinking water.  

                  At 25% it is harmful to the environment, can cause extremely nasty burns to skin and is highly corrosive. At 15%, the strength most commonly available, it will also cause skin irritations and is classed as corrosive. At 10%, the strength of concentrated Benz Blackwash, it is much less irritating and only slightly corrosive. 



                  At concentrations of 2%, which is the level Benz Blackwash diluted at 5:1, sodium hypochlorite is not corrosive to metals and there are no expected skin irritations based upon a 24 hour contact time



                  A note about drains:
                  It is important to protect our environment by minimising run-off into sewers and surface drains. Run-off can be kept to minimum or zero by using BENZ Nozzles along with skillful spray and brush control techniques. If some run-off to drains is unavoidable, block the drains and/or gutter downpipes until application has been concluded.

                  Low environmental impact:
                  At 0.5-2% concentration, sodium hypochlorite is unclassified. Therefore using BENZ Blackwash at a 5:1-10:1 mix, the heavily diluted rinse residues from hard surface cleaning can be washed into foul drains – where the very small amount of remaining chemical rapidly breaks down upon contact with organic matter.

                  • Benz Blackwash does not bioaccumulate, is unclasified in use under EU legislation, and therefore does not pose an environmental risk.

                   

                  Smell & Fragrance: In its pure form there is a slight smell that some people find unpleasant. So we add a fragrance to Blackwash to make the process of stain removal more pleasant for both end customers and operatives.

                  Btw: Our comparision tests with other commercially available surfactant/fragrance combinations, which are added to industrial grade 15% chlorine sodium hypochlorite, showed that they do not adequately mask the odour of chlorine.

                  This means that in use there is a highly unpleasant "bleach" smell.

                  We've also noticed during our tests that the quality of surfactant often is simply not up to the job.

                  In contrast we estimate that Blackwash is about 10 times more pleasant to use. Indeed, some people have commented that the aroma that can be detected when treating large areas can actually be quite agreeable.


                  Available Chlorine: Commercial sodium hypochlorite has 10-15% available chlorine. Domestic bleach has 5%. And Benz Blackwash in use has only 0.5-2%, which makes it safe for humans and for our environment.

                  Non-carcinogenic: Sodium hypochlorite at the levels used in Benz Blackwash is "not classifiable" as to its carcinogenic effect on humans.


                  Benz Blackwash diluted at 5:1 has a sodium hypochlorite strength of only 1-2% (similar to babies bottle sterilising fluid) – and we often use it at 10:1

                  What cleaning projects can Benz Blackwash be used for?

                  • Coloured and plain render
                  • Painted surfaces
                  • UPVC
                  • Industrial piping and tanks
                  • Timber structures – decking, sheds, fencing
                  • Paths, drives, and patios

                  Blackwash is best applied using a low-pressure spray system. Then simply rinse off using a garden hose or, on suitable surfaces, a power washer using low pressure and/or a fan jet.

                  Btw: Blackwash has an alkaline pH and surfactant, which, along with the agitation of spraying and gentle brushing, loosens the biological growth and helps facilitate its removal during rinsing

                  A maintenance spray with Benz Biocidal Wash every 1-3 years should be enough to keep most surfaces permantly clean.

                  Test before applying: Always test a cleaning chemical on a small, obscure area of the surface to be cleaned if you are not familiar with the effect of the chemical on that particular surface.

                  Applying to metals: The same advice to test before applying a cleaning chemical applies to metals. We recommend wetting metal surfaces before applying a cleaning chemical to prevent streaking.

                  Coverage

                  Typically 30-40L will be used by a one-man contractor per day to treat all the elevations of a large detached house, including the paths and drive. Some jobs may require as little as 5L, while large contractors can use up to 100L per day. 

                  As a rough guide, 5L of Blackwash will create 30L of mix, which will treat 40-50 square metres of a porous surface at 5:1 and double that at 10:1.

                  The coverage of Blackwash is dependant on many factors, such as:

                  • The porosity of the surface that, in effect, increases the surface area (think honeycomb).
                  • The type and amount of soiling.
                  • The method of application, i.e. by brush, spray, or watering can.


                  Again as a rough guide, 10L Blackwash will make 60 litres of mix at 5:1, which will be enough to clean a very dirty (needing two applications) large gable end of a rendered house. It would also be sufficient to clean an average two-car Cobblelock driveway.

                  10L Blackwash will make 110L mix at 10:1. On smooth, non-porous surfaces such as cladding or painted surfaces this quantity will clean approximately 300 square metres, which is about three times the amount of cladding cleaned in the cladding cleaning guide photos on this website.

                  Back to Top

                   

                  Why is rinsing Benz Blackwash important?

                  Always thoroughly rinse Blackwash from the surface being treated after allowing 30-60 minutes for the cleaning action to take effect.

                  This ensures the salts left behind by the breakdown of chlorine, which could potentially damage the surface if left, are removed.

                  Also, we advise rinsing between applications of Blackwash. On many jobs only one application is sufficient. But if the staining is bad, two treatments – and exceptionally three – may be required.

                  Rinsing off the previous coating of Blackwash removes the "debris" from the pores of the surface, thus allowing subsequent applications to penetrate more deeply and clean more effectively.

                  If you are going to apply Benz Biocidal Wash following a Blackwash treatment it is important to give an especially thorough rinsing. This is to remove any surfactant that may be left behind, which could impede the Biocidal Wash being fully effective.

                  On porous surfaces we recommend spraying the first treatment, then gently brushing each subsequent application of Blackwash into the surface. This allows the product to penetrate the biological growth to the maximum depth, increasing its effectiveness.

                  How to store and use Benz Blackwash for best results?

                  • Store in a cool, but not freezing, environment away from direct sunlight.
                  • For best results use within two months of manufacture (date is on side of container).
                  • Once opened use within 2 weeks.
                  • Always store Blackwash in the original containers, which are specifically designed for maximum safety and longevity of the product. They come with special vented caps that allow for the gradual and safe release of a small amount of harmless vapour that all sodium hypochlorite based products naturally produce.

                    Benz containers are industrial strength and have been drop-tested. This means they can withstand the sometimes harsh conditions of on-site use, and storage in vans along with other equipment, without splitting.

                    Btw: Some companies cut corners by supplying weaker containers to make their products cheaper. But we believe the potential health and safety hazards these create, along with the financial cost of leakages, mean they are a false economy.


                    Protect Benz Blackwash from heat

                    Keeping Blackwash cool will greatly extend its shelf-life

                      • Vans can get very hot inside during the summer months, so we suggest removing the Blackwash container from your van and placing it in a shaded area on the site.
                      • Metal and wooden sheds can also heat up, so find a cooler location for long-term storage.
                      • Use a an old insulated chest freezer: This will keep Blackwash cool, away from sunlight, and ensures chemicals are kept away from children, pets and the general public. Don't freeze Blackwash; just keep the inside of the freezer cool, not freezing.
                      • Use a picnic cool box: These can work well, especially if you add an iceblock, and can accomodate a couple of 5L containers. Great for summer days when you only need to take 5L containers onto site.

                        Health & Safety

                            • Do not pour water into undiluted Blackwash. Always half-fill your tank with water, add the required quantity of Blackwash, then complete filling your tank with water.
                            • NEVER mix Blackwash and Biocidal Wash together as toxic chlorine gas may be produced.
                            • ALWAYS thoroughly rinse all application equipment and tanks before changing from Blackwash to Biocidal Wash, and vice-versa.
                            • The public and animals should be excluded by barriers and tape from areas where spraying, mixing and storage of chemicals is taking place. Children and animals must be excluded from the working area until the chemical treatment is dry. If a human or animal comes into contact with a soft wash chemical the area of skin contact should be immediately rinsed with fresh water.
                            • Use respiratory protection in confined areas: If Blackwash were to be used indoors (a purpose that is not its intended use and which we do not recommend), or in an external but confined area – appropriate breathing apparatus should be worn.

                        When working with chemicals always keep your equipment and personal protection equipment (PPE) clean. Take care to protect yourself from accidental contact with your eyes and skin. Wear chemical resistant protective gloves, and chemical resistant clothing that covers your whole skin surface, and a full face visor that includes protection for your hair. Wash all PPE with fresh water before taking breaks, before eating, drinking and smoking, and at the end of each working day.

                        Always treat a small, obscure test patch on a customer's property before using any chemical cleaning product and obtain your customer's agreement that the effect of the applied chemical is acceptable before cleaning the entire property.
